Maintaining transparency for use in another project
I have created a spinning logo/bug on a transparent background – that needs to become part of a background for a powerpoint slide. Everything I have tried results in a white background upon completion. One, can the transparency be maintained during render, and two am I completely out of the ballpark on this one?

Typically you would need to render as Quicktime movie with Alpha channel (Millions of Colors+) enabled. However, if you want to throw this into PowerPoint you’re basically out of luck, as PowerPoint does not respect alpha channels when playing back movies. In addition, PowerPoint would not let you put anything on top of the video, so if it is to serve as part of the background your clients may have another problem there.
It just so happens that my company has developed a solution for this troublesome (and rather well known) PowerPoint shortcoming. Our product is not launched yet and anyway I don’t wish to self-promote here, but if you contact me directly at

I’ll be glad to try and help solve the problem.

Ok, so basically I think I am having the same problem. But instead of alpha channeling I was wondering if chroma keying registers into ppt. I am using After Effects on a video to key out the green screen, then trying to input that video onto a ppt slide like this example https://www.youtube.com/watch?v=dgy41dLAqb0.
The PPT program I am using is for PPT X on Mac.
Thanks for the help!
